exida Announces Safety Lifecycle Web Series
May 25, 2011
In recent years, both the IEC 61508 and IEC 61511 standards have been adopted and are rapidly gaining momentum. These standards address both equipment design and system implementation, and have broad implications on Safety Instrumented Systems (SIS).
The safety lifecycle can be segmented into three phases:
1. Analysis
2. Design
3. Operation
Each phase addresses specific issues important to achieving a high level of functional safety. By gaining a better understanding of each phase, you will learn to implement high quality safety systems more effectively and efficiently.
The Safety Lifecycle in Three Phases
Wednesday, June 15, 2011: Safety Lifecycle I: The Analysis Phase
Instructor: Chris O’Brien
Session 1: 10:00am-11:00am EDT
Session 2: 4:00pm-5:00pm EDT
The first seminar in this Web Series will highlight the Analysis Phase. The Analysis Phase addresses the activities starting with the risk analysis of the process through creation of the safety requirement specification. Areas addressed in the Analysis Phase include:
• Risk Analysis
• Protective Layer Design
• SIL Targeting
• SRS Requirements
Thursday, June 23, 2011: Safety Lifecycle II: The Design Phase
Instructor: Chris O’Brien
Session 1: 10:00am-11:00am EDT
Session 2: 4:00pm-5:00pm EDT
The second seminar in this Web Series will highlight the Design Phase. The Design Phase addresses the activities starting with the conceptual design of the safety instrumented system through the validation of the completed system. Areas addressed in the Design Phase include:
• Conceptual safety instrumented system design
• Selection of system technology, architecture, and test philosophy
• Equipment selection
• SIL verification
Thursday, June 30, 2011: Safety Lifecycle III: The Operations Phase
Instructor: Bill Goble
Session 1: 10:00am-11:00am EDT
Session 2: 4:00pm-5:00pm EDT
The third and final seminar in this Web Series will highlight the Operations Phase. Safety Integrity depends on the test and maintenance activities in the operational phase of the safety lifecycle. No design, no matter how good, can provide protection when it is disabled or degraded. The primary challenge is effective proof testing which is not cost effective but actually finds problems. Many of the conventional test techniques are only partially effective and costly to perform.
This web seminar discusses all the activities of the operation phase of the safety lifecycle but focuses more on commissioning test and periodic proof testing. New techniques based on the latest FMEDA results show how to design more effective proof tests that can take less time.
